Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Referring to Fig. 1, the better embodiment of the present invention provides a kind of radio frequency identification control system 100, and it is for logistics, the field such as antitheft, false proof, to read the unique identifier in the electronic tag attaching on different article.In the present embodiment, it is illustrated as a example by being applied to logistics field.Described article are centrally located in a transfer house, on each article, all correspondence attaches an electronic tag, store a unique identifier in this electronic tag, the Air Way Bill No. of the recordable article of this unique identifier, need the information such as the place being dispatched and time of leaving a transfer house.
This radio frequency identification control system 100 includes fixed type reader-writer the 10th, hand-held read-write the 20th, radio-frequency module 30 and induction module 40.This radio-frequency module 30 is arranged on hand-held read-write 20, and this induction module 40 is arranged on fixed type reader-writer 10.
In the present embodiment, the operating frequency of this fixed type reader-writer 10 is about 902-928MHz(and belongs to hyperfrequency, UHF).This operating frequency can support higher message transmission rate, it is adaptable to logistics field, and it reads and writes radius preferably from about 3m.This fixed type reader-writer 10 may be disposed at the doorway of transfer house, for being read the corresponding unique identifier of article of this transfer house into/out by REID, and on this article attach electronic tag in write relevant information, for example write article this transfer house into/out time.
This fixed type reader-writer 10 includes main control chip 12 and indicator elment 14.This main control chip 12, for the control signal (describing in detail afterwards) transmitting according to induction module 40, is in work or break-off two states to control this fixed type reader-writer 10 further.Meanwhile, this main control chip 12 and this indicator elment 14 are electrically connected with, and are used for sending voltage signal to indicator elment 14, and then enable or do not enable indicator elment 14.In the present embodiment, this indicator elment 14 is light emitting diode (LED), and when fixed type reader-writer 10 works, this lumination of light emitting diode, when fixed type reader-writer 10 break-off, this light emitting diode is not luminous.
In the present embodiment, the operating frequency of this hand-held read-write 20 is also about 902-928MHz, and it reads and writes radius preferably from about 3m.This hand-held read-write 20 is for reading the unique identifier of the article in transfer house one by one, with the independent information obtaining each article, it is simple to check, sorting articles.One switch key 22 is set on this hand-held read-write 20, can control this hand-held read-write 20 by this switch key 22 and be in work or break-off two states.
In the present embodiment, this radio-frequency module 30 is about the electromagnetic wave of 2.45GHz for Radiation work frequency, and its radiation radius determines according to the read-write radius of fixed type reader-writer 10 and hand-held read-write 20, is i.e. less than or equal to the read-write radius sum (about 6m) of the two.This radio-frequency module 30 is located on hand-held read-write 20 and is electrically connected with hand-held read-write 20, to obtain operating voltage from hand-held read-write 20.This radio-frequency module 30 is also electrically connected with switch key 22, to work under the triggering of switch key 22.For example, when switch key 22 is pressed, hand-held read-write 20 is in running order, and provides operating voltage for radio-frequency module 30；Simultaneous Switching button 22 triggers a signal of telecommunication to radio-frequency module 30, starts radiated electromagnetic wave to control radio-frequency module 30.When switch key 22 is depressed again or is released, hand-held read-write 20 is in pause mode and will not provide operating voltage for radio-frequency module 30, Simultaneous Switching button 22 triggers another signal of telecommunication to radio-frequency module 30, to control radio-frequency module 30 non-radiating electromagnetic wave.On the other hand, owing to this radio-frequency module 30 differs relatively big with the operating frequency of hand-held read-write 20, therefore without interference with this hand-held read-write 20.In like manner, this radio-frequency module 30 is also without interference with fixed type reader-writer 10.
This induction module 40 is located on fixed type reader-writer 10 and is electrically connected with main control chip 12.In the present embodiment, this induction module 40 is for sensing the electromagnetic wave of 2.45GHz, and when sensing the electromagnetic wave of this 2.45GHz, trigger a control signal (such as low level signal) to main control chip 12, and when being not sensed by the electromagnetic wave of 2.45GHz, trigger another control signal (such as high level signal) to main control chip 12.
Illustrating the operation principle of this radio frequency identification control system 100 further below: when there being article to enter this transfer house, this fixed type reader-writer 10 reads the unique identifier of article, and will enter in the relevant information write article such as the time of this transfer house.Additionally, this hand-held read-write 20 is started by switch key 22, to read the unique identifier of the article in transfer house one by one, to check, sorting articles.
When hand-held read-write 20 and fixed type reader-writer 10 are distant, for example distance is more than 6m.Owing to this distance exceedes the read-write radius sum of hand-held read-write 20 and fixed type reader-writer 10, therefore the two will not interfere and normally work.Simultaneously, owing to this distance exceedes the radiation radius of radio-frequency module 30, make induction module 40 because the electromagnetic wave that radio-frequency module 30 radiates can not be sensed, and to main control chip 12 Trig control signal (such as high level signal) so that main control chip 12 controls fixed type reader-writer 10 maintenance work state.Main control chip 12 enables indicator elment 14(such as LED lighting simultaneously) to point out stock clerk's current fixed type reader-writer 10 working properly, can continue to be stored in article in transfer house.
When hand-held read-write 20 is near fixed type reader-writer 10, for example distance is less than 6m.Now, owing to induction module 40 can sense the electromagnetic wave that radio-frequency module 30 radiates, and to main control chip 12 Trig control signal (such as low level signal) so that main control chip 12 controls fixed type reader-writer 10 and is in pause mode.Therefore, hand-held read-write 20 will not be worked on by the interference of fixed type reader-writer 10.Simultaneously indicator elment 14 will not be enabled by main control chip 12 (as diode is not luminous) to point out stock clerk current fixed type reader-writer 10 break-off, temporarily article can not be stored in transfer house.So, this hand-held read-write 20 and fixed type reader-writer 10 all will not be because of skip or the unique identifiers misreading article by interference each other.
It is appreciated that when hand-held read-write 20 is near fixed type reader-writer 10, it is possible to close hand-held read-write 20 to avoid interference fixed type reader-writer 10 by switch key 22.
The radio frequency identification control system 100 of the present invention is by arranging radio-frequency module 30 on hand-held read-write 20, and arranges induction module 40 on fixed type reader-writer 10, to sense the electromagnetic wave being sent by radio-frequency module 30.So, when hand-held read-write 20 is near fixed type reader-writer 10, induction module 40 sends control signal to main control chip 12, to control fixed type reader-writer 10 break-off.Obviously hand-held read-write 20 can be made will not to interfere with fixed type reader-writer 10 by this radio frequency identification control system 100, will not skip or the unique identifier misreading article, improve the efficiency of logistics transportation.
